ELLA E. BRIGGS, OF ST. LOUIS, MISSOURI.

ATTACHMENT FOR 'I'YPEWRITERS.

Specification of Letters Patent.

Patented Aug. 30, 1921.

Application filed December 29, 1920. Serial No. 433,830.

To all whom it may concern Be it known that I, ELLA E, BRIGGS, a citizen of the United States, residing at the city of St. Louis and State of Missouri, have invented a new and useful Attachment for Typewriters, of which the following is a specification.

This invention relates to attachments for typewriters, and consists in the novel construction hereinafter shown.

In the instruction of typewriting by what is commonly known as the touch system, it is an advantage to shield the key-board from the vision of the operator and to divide the key-board so that the several keys may be more conveniently located by the operator.

An object of the invention is to provide a shield and divider that may be conveniently attached to the key-board of the standard type which will be efi'ective to shield the key-board from the vision of the operator and to divide the key-board into two sec tions.

Additional advantages of the construction will be apparent from the following detailed description thereof taken in connection with the accompanying drawing, in which- Figure 1 is a front elevation of the keyboard of a typewriter showing the attachment of the present invention applied thereto.

Fig. 2 is a side elevation.

Fig. 3 is a erspective view of the attachment remove from the machine.

In the embodiment of the invention illustrated in the drawing the attachment comprises a back wall 1, the upper edge of which is down-turned and extends forwardly from the back wall in an inclined position forming a hood 2 that projects over and obscures the key-board from the vision of the operator. An edge of the hood 2 has an up turned flange 3 so that in addition to constituting a shield to obscure the key-board from the vision of the operator, it may be conveniently used for a rest to support the typists notes or manuscripts in such a position that it may be readily read by the operator.

The back wall 1 is formed with a notch 4 so that it may be positioned against the typewriter frame in back of the key-board.

ackward'ly extending spring clips 5 are provided to removably engage the attach ment with the frame of the typewriter.

Attached to the front face of the wall 1 is a downwardly extending and laterally deflected partition wall 6, the bottom edge of which is so formed that it may be positioned in the interval between the central rows of keys in the key-board. This partition 6 divides the key-board into two zones, one operated by the right hand of the operator and the other by the left hand:

It is preferable that the entire attachment be made of metal, although other material may be employed if desired.

hat I claim and desire to secure by Letters Patent is l. An attachment for typewriters, com- EIISlIlg a supporting member arranged to ear against the frame of the machine above and behind the keyboard, releasable spring clips supported by said member, and arranged to engage the frame of the machine, and a partition supported by said supporting member extending obliquely down- ;Ivardly and forwardly between the rows of eys.

2. An attachment for typewriters, comprising a vertical partition wall extending rearwardly from point in front of the front row of keys and extending upwardly above the planes of the rows of keys, an element in connection with said partition wall resting against the front of the typewriter frame, and a device at each end of said elcment for releasably engaging the typewriter frame above the partition wall.

3. An attachment for typewriters, comprising a support resting against the front of the typewriter frame behind the keyboard, a partition wall extending downwardly and forwardly from said support between rows of keys, a screen extending downwardly and forwardly from said support above said partition wall and below the top of the typewriter frame, and a device pivoted at each end of said support for engaging the typewriter frame below said screen and below the top of the typewriter frame.

4. An attachment for typewriters. comprising a support bearing against the front of the typewriter frame, a screen extending downwardly and forwardly from the upper part of said support and below the upper portion of the typewriter frame, elements in connection with said support below said screen engaging the typewriter frame, and a partition wall extending obliquely laterally and forwardly between rows of keys below said screen.
